Two tricyclic orthoesters and three other orthoesters have been submitted to acid hydrolysis conditions to yield mixtures of lactones and esters. The ratios of different products have been rationalized in terms of stereoelectronic, steric and entropy effects at the various steps. A quantitative AM1 investigation has been carried out, starting from the only tricyclic hemi-orthoester intermediate of the whole system, in order to compare the hydrolysis routes leading to the kinetic and thermodynamic lactone products.
